Description
Returns a column vector containing the product of
p and q as
polynomials
,
where both p and q are real, double-precision,
or complex column vectors.
The return value has the same type as a binary operation between
p and q.
(See the coercion
entry in the O-Matrix User's Guide.)

This function computes the result directly using the
intrinsic function filter
.
The conv
function computes this product using an FFT.
